Short summary
We computed a global map of crustal thickness covering the entire Antarctic continent from GOCE satellite gravimetric data. We compare our result to seismological models: a fairly good agreement is shown. However, better resolution is obtained using the gravity observations than using only seismological ones. This research will help us to understand the geology of Antarctica.
